\b[Andrew Schally] studied how the <hypothalamus> controls secretion by the <pituitary gland> through small <peptides>. His work helped establish a chemical connection between brain activity and the release of <hormones>, and he shared the 1977 Nobel Prize in Physiology or Medicine for discoveries concerning brain peptide hormone production. He worked at Tulane and the Veterans Affairs hospital in New Orleans for more than four decades.<Dr. Andrew Schally, former Tulane endocrinologist and Nobel laureate, dies at 97 by Tulane University>[institutional obituary, career and hypothalamic peptide research]{ref}
One important experimental question was whether separate hypothalamic signals were needed for the two <gonadotropins>, <luteinizing hormone> and <follicle-stimulating hormone>. Schally and colleagues' 1971 report described a purified hypothalamic factor that stimulated both. This connected a chemically characterized signal to two measured <pituitary gland> responses and helped establish the role of <gonadotropin-releasing hormone>.<Hypothalamic follicle-stimulating hormone (FSH) and luteinizing hormone (LH)-regulating hormone: structure, physiology, and clinical studies by Andrew Schally and others>[abstract, hypothalamic factor stimulating both gonadotropins]{ref}
